GEORGE w. DONNING, OE EAs'r ORANGE, NEWv JERSEY, AssIGNOR To HARRY T.AMRRosE, OE ORANGE, NEW' JERSEY PAPER FEEDING AND CONTROLLING DEVICE.

SPECIFICATION forming part of Letters Patent N0. 791,187, dated May 30,1905. Application filed February 14, 1903. Serial No. 143,421.

The object of this invention is to provide means for tensioning thecarbon or other paper foruse, especially in type-writing ma-v chineswhich print upon the work in a flat form.

Another object is to provide means for frictionally controlling thefeeding of the carbonpaper in such devices from the tension-roll.

Another object is to provide means for carrying the carbon or otherpaper, said means provided with ends detachably and yieldinglydisposed`in a support.

Another object is to provide as an article of commerce a spindle forcarrying a carbonsheet, said spindle having yielding ends to beremovably secured to a shaft carried by the machine.

Another object is to provide a carbon-carrying spindle disposed upon ashaft and means for operatively securing the spindle and shaft.

Another object is to provide a carbon-carrying spindle, a shaft uponwhich the spindle is supported, and means for securing the spindle uponthe shaft in such manner as to permit adjustment of the same upon itsshaft for diderent widths of carbon, whereby the car-v bon may bepositioned at any predetermined point. y

Another object is to provide means for maintaining the carbon or writingmaterial taut while the opposite end of the same is being raised toseparate it from its contacting paper sheet.

With these objects in view and others my invention comprehends thedetails of construction, arrangement, and combination, as

carbon-sleeve clamp. Fig. 4 shows the tension-sleeve. Fig. 5 shows thetension-drum in section. Fig. 6 shows the tension-drum in elevation.Fig. 7shows the winding-spring; and Fig. 8 is a side elevation of thedevice, showing the carbon-sheet-raising means. Fig. 9 is a view infront elevation, in detail, of a split sleeve and its encircling collardisposed within its tension-drum. Fig. 10 is a view in perspective of asplit sleeve alone, the

split side thereof appearing at the front.

In the several Views of the drawings, in which the characters ofreference indicate the same parts, A is a shaft supported bybearing-blocks a a2, one bearing being slidable, so as readily to removethe shaft when desired. The bearing-spindle A2 is retained in engagementwith the shaft A by a helical spring A3, against the force of which itmay he withdrawn by the knob Af. By this means the shaft is normallyheld against rotation-that is, its rotation is retarded to preventundesirable movement of the same.

A sleeve B is slidably mounted on the shaft A and has a ring or collar Csecured to one or both ends. A knurled headed set-screw O2 is threadedin each collar and may pass through slots and engaging theshaft A securethe sleeve in various positions along the shaft. Instead of having theslots the screws may bear on the sleeve B and press it against theshaft, and the sleeve may be of less thickness where engaged by thescrews. Preferably this sleeveV is non-rotatably secured to the shaft bymeans of the collars C and the set-screws C2, though it is obvious that,if desired, said sleeve may be arranged to rotate upon said shaft A.

vOn one end of the shaft AA is arranged a split sleeve G, whichis'preferably madeof a diameter somewhat less than the diameter of(which has one end secured to the drum and the shaft A and has a slot gextending throughout its entire width, and the same is thus frictionallyretained on said shaft A, the frictional resistance thereof beingsufiicient to retain this sleeve G in a fixed position upon the shaft,except as hereinafter stated. Surrounding this sleeve G is a rotatablecollar D, preferably of the same width as the sleeve and provided with apin or screw o2 at one end which extends into the slot g in the sleeveG, so that as said sleeve is rotated the collar D is rotated therewith.Rotatably surrounding the rotatable collar D is a rotatable drum E, andbetween this drum and the collar D is connected an evolute spring F,which encircles the collar D. Secured exteriorly on the drum E is astop-pin a3, which is designed to strike a pin f, disposed on thebearing-block a in the path of said pin a3, whereby but one revolutionof the drum is permitted. Within the drum and preferably formed as anextension of the pin a3 is another pin a4, which is arranged to strikeagainst a screw or pin d, preferably threaded into the enlarged portionof the collar D beyond the pin or screw (Z2, and limits the extent ofrotation of the -drum E on the collar D. A disk F2 closes the drum E atone end.

The length or breadth of carbon or other paper H is wound or supportedon the sleeve B and the end thereof passed over the platen I and thensecured to a suitable clamp /c and member K on the machine.

It is to be understood, as already pointed out, that the split sleeveGis only frictionally mounted on the end of the shaft A, the frictionalresistance thereof being sufficient to retain this sleeve in a fixedposition upon the shaft A as against the action of the tensionspring E,as hereinafter described.

Now the carbon or paper is wound upon the sleeve B in such directionthat in unwinding it will be drawn forward toward the clamping member7a, and this operation will cause said sleeve B and the shaft A (thesleeve B being preferably non-rotatably secured to the shaft A) torotate slightly and permit the unwinding of the paper from said sleeve.During the rotation of this sleeveB and shaft A the split sleeve g (atthe end of said shaft and which, as already stated, is frictionallymounted on said shaft) is also given rotation, and this rotates thecollar D and drum E until the pin a3 on the drum strikes the pin f onthe block a, which stops further rotation of the drum. Then the collarD, its sleeve, and the shaft continue to rotate until the screw or pin Zstrikes the pin projecting Within the drum E. This prevents furtherrotation of the collar D and sleeve Gr. Now` when the drum has beenstopped in its revolution, as just described, by the pins a3 and fengaging and while the collar D is continuing its rotation within thisdrum the spring F veins? the other to the collar D) is caused to betensioned until the pin d strikes the pin a?, whereupon if the pull onthe paper or carbon is discontinued said spring will cause rotation ofsaid collar in an opposite direction, and this rotates the sleeve G andshaft A until the screw or pin d impinges against the pin a on itsopposite side. This stops further rotation of the shaft A in thatdirection, and thereby prevents the entire winding up of thc carbon uponthe sleeve B upon release of the carbon at its free end intentionally oraccidentally. 1f, however, the pull on the carbon or paper is continuedafter the spring is tensioned, the sleeve Gr by reason of its being onlyfrictionally mounted on the shaft A will yield and permit the shaft Atorotate within this sleeve G on its end bearings without disturbing thetensioning device, which when the pull on the paper or carbon isreleased will tend to rotate the shaft in the opposite direction, asjust described. Then the end of the carbon-paper has been secured in theclamp L, the spring F, which has been put under tension, as justdescribed, will unwind and rotate the shaft in a direction opposite tothat in which it has been pulled until such rotation is stopped, asabove described, to prevent the entire winding up of the carbon upon thesleeve B, and this operation takes up any slack in the carbon-sheet andkeeps it drawn taut across the platen.

By the construction I provide a means for exerting a constant drawing orpull upon the paper in a direction opposite to its feeding, with a Viewnormally to maintain the paper taut across the platen, and thus removeall slack therefrom.

The clamp 7c on the member K may, if desired, be part ofa carbon-sheetseparator, such as described in a concurrent pending application of mineserially numbered 142,787, liled February 10, 1903, and the deviceherein set forth is designed to be employed in connection therewith, sothat when the operation of separating the carbon from the paper isoccurring the carbon-sheet is held perfectly taut, though yieldingly so,in its several positions.

After a portion of the paper is used or worn a fresh portion is unwoundand drawn over the platen and clamped at when the used part may be tornor cut oli. It will be observed that while the paper is unwinding fromthe roll A the spring will constantly keep the roll under tension,tending to wind it up again for almost a complete revolution; but if toomuch slack has been provided, so that the one revolution given to theroll A is not suiicient to take up all the slack when the end has beenclamped at the tensioi'i-screws C can be loosened and the roll A turnedback to wind up the paper again, when the screws can be set again.

It is to be understood that this device, either by itself or combinedwith the carbon-separato'r aboveireferred to, may be employed inlconnection with an ordinary writing pad or book where a plurality ofautograph or other copies are to be made.
